The Enzyme Commission numbers for oxidoreductases start with the number 1.

https://en.wikipedia.org/wiki/List_of_EC_numbers_(EC_1)

1. Glucose oxidase (GOx) - catalyzes glucose oxidation

2. Lactate oxidase - catalyzes lactate oxidation

3. Monoamine oxidase (MAO) - catalyzes amine oxidation

4. Cytochrome c oxidase - catalyzes electron transfer in cellular respiration

Oxidoreductases catalyze redox reactions, where the transfer of electrons or hydrogen atoms occurs between molecules. These reactions include:

1. Dehydrogenation: Removal of hydrogen atoms (e.g., lactate dehydrogenase converting lactate to pyruvate).

2. Oxidation: Addition of oxygen or removal of electrons (e.g., alcohol oxidase oxidizing ethanol to acetaldehyde).

3. Reduction: Addition of electrons or hydrogen (e.g., nitrate reductase reducing nitrate to nitrite).

4. Hydroxylation: Incorporation of hydroxyl groups (e.g., phenylalanine hydroxylase converting phenylalanine to tyrosine).

These enzymes include oxidases, reductases, dehydrogenases, and peroxidases.
